What type of PR is this?

/kind feature
/milestone 2.12.x
/area core

What this PR does / why we need it:

我们为文章自定义模型的数据调协过程引入了重要的优化。
在以前,当数据量大(例如,50,000篇文章)的情况下,每次系统重启都会触发耗时且资源密集的所有数据的协调过程,即使大部分数据并不需要调协。这导致了不必要的数据库查询和高资源消耗。

为了解决这个问题,我们在文章自定义模型的 status 中添加了一个新的 Long observedVersion 属性。
每次协调后,此属性将更新为 metadata.version,还调整了 syncAllOnStart 条件,只有当 status.observedVersion < metadata.version 时才会调协数据。

这个改变确保了只有在启动时需要的数据会被协调,从而减少了资源使用和不必要的协调过程。
因此,Halo 的数据承载能力得到了显著提高。

how to test it?
使用此 PR 测试:启动时文章只有首次会执行 reconcile,再次重启时则不会再执行,如果直接修改数据去除掉 status.observedVersion 来模拟迁移或漏 reconcile 的过程则启动时该数据会被再次执行 reconcile

Which issue(s) this PR fixes:

Fixes #5147

Does this PR introduce a user-facing change?

优化文章数据的调协过程以降低 Halo 启动时文章的调协耗时同时提高性能和资源利用率

文章数据(包括量非常大其他数据)倾向启动时不同步数据。

文章数据(包括量非常大其他数据)倾向启动时不同步数据。

建议可以测试一下,只有漏跑的才会在启动时被执行,否则等于启动时没有执行同步,除此之外没有任何副作用

如果启动时不同步那么当创建了文章堆积在 queue 里没有执行 halo 被停止了怎么办呢,文章就只能手动更新才可以再次执行

不同步数据的副作用肯定是有的,就如你上面所提到的。

我的关注点在数据量上,如果数据量本身可能会无限增长,此时就不再适合用 Reconciler 来实现相关逻辑,例如文章,评论等数据。尝试用另外的方式实现文章的发布,更新及删除等可能会更好。

但是通过此 PR 解决了启动时不同步又没有副作用的情况下,无论数据怎么增长都不会影响到启动吧,添加一篇文章 Reconciler 就处理一篇是没有问题的处理完之后启动时就不会在无效执行,没理解你考虑的点在哪里

Note 当用户升级到 2.12 之后对于以前的文章数据启动时还是会同步一次,但是之后在重启或升级就不会在启动时被执行了
